Windows: If you've upgraded to Windows 8 but would love a tool that makes it easier to tweak the OS to your liking or puts some of Windows' most common options at your fingertips, EnhanceMy8 will do the trick.

EnhanceMy8 lets you create restore points before you make system changes, and lets you quickly change applications that run at startup, identify running processes and tie them back to their originating applications, and enable or disable WIndows 8-specific settings and features that you may or may not need. Even if you don't get deep into the tweaking tools, the app's main screen shows you a ton of valuable information about your PC and its components.

Like many system tweaking and maintenance tools, EnhanceMy8 offers a number of built-in tools and quick access to Windows' built-in options that are buried in menus. For example, EnhanceMy8 gives you one-click access to Disk Cleanup and Disk Defragmenter, Security tools and options, and other options buried in the Charms Bar and its menus. There are two versions of the app—the free version that limits some features and a $30 Pro version that unlocks everything. Try the free version first to see if you really need the options available in the paid version.
